DETROIT, MICHIGAN A GORPQBATIQNOF EIICI-IIGAN wmnow CONSTRUCTION Application filed January 11, 1929. Serial No. 331,923. Renewed July 7, 1930.

The present invention pertains to a novel window constriction of a type which may be installed in old buildings as well as new and which is adaptable to every type of'building construction ranging fromdwelling house to skyscraper'ofiice or apartment building.

The primary object "of the invention is to' devise a window capable of providing as nearly perfect ventilation as it'is' possible to secure. For providing this. ventilation the lower sash is pulled inward-1y atthe top. and automatically locks itself in a position which provides adequate ventilation With-out causing a draft or without admittingtheelelaments.

A further object of the present invention is to eliminate the unpleasantness and chiliculties found in washing and cleaning the outside of the windows and thereby transform one of the most disagreeable of household tasks into one ofthe easiest." In accomplishing this object, the devicefis so constructed that a mere'touch on a springatthe top of the sash causes the sash to be released 2 whereby it may be pulled inwardly at the top to swing upon a pivot at its lower end to lie fiatatthe proper height for cleaning. A still'further'object of the present invention is to construct a window capable of performing the above objects which will not interfere in any manner withouts'idescreen's while inthe position for supplying ventilati on or the horizontal position for permitting cleaning of the glass. f

VVith these .objects in view and others which are subsidiary thereto or resultant therefrom and which will become apparent as the several elements and; their functions are-enumerated and set forth, the invention is fully disclosed and set forth in the following description, reference being hadto. the accompanying drawings, in which 1 q Figure 1 is an elevation ofa window comq plete with frame and sash, the sash being constructed in accordance {with the present invention; f I r Figure'Q is afragmentary end view of the window sash; o

Figure 3 1s a fragmentary view of the 5 sash and frame, partly in cross section;

novel. the screws 4, the plate having'the tongue 5 ing the sash maintained in the ventilating p0-' siti on.

Numerals are employed throughout the followlng description and accompanying drawrings and serve to indicate the corresponding the present invention. 7 c

The numeral 1 indicates the windowframe which might be any convenientdouble hung window frame for the urpose of slidably supporting sashes 2 anc inasmuch :as the parts and elements which combine to form mechanisms upon; both the upper and lower.

sashes are identical it will be necessaryto describe only one in detail. The sash 2 is ordinarily formed of woodbut it is not neces- 'sary for the purpose of the present invention that it should be as a metal sash would operate with equal satisfaction. r Although the particular type of sash illus I Figure 4 is a transverse cross sectional view trated is old and well known, it will be described in order that a clearer understanding may be had of the mechanism which is The sas'h2 has a plate 3 secured by which engages in the groove fiformedon the channel member 7 to form a weatherproof strip which will allow thevwindow to only break inwardly. received between the rails 8 of the window The channelmember 7 is frame topermit them to be raised or lowered and any suitable type of balancing-mechanism may be emp'loyed :to assist easy raising and lowering. a Thelower end of the channel member 7 is provided with a slot 8 which has an angular slot 9 branching at right angles therefrom in order to form the shoulders 10 and 11.

The slot receives a lug 12attached firmly to the plate 3, the lug being rectangular. in cross section and adapted to act as a pivot for the sash 2 by engaging with the rounded portionlgattheupper end of the slot 8 where it joins i 3:

the slot 9, the opposite side of the slot being enlarged as at 14: to permit the lug 12 to turn freely and engage the shoulders 10 and 11. The lug 12, being firmly secured to the sash by means of the plate 3, will maintain the sash horizontally when it engages the shoulprises a pivot pin 15 upon which is pivotally mounted an arm 16 having fingers 17 adapted to engagea stud 18 formed on the lug 12. A

. lever 19 is also pivotally carried by the pin 15 and is adapted to be engaged by a finger 20 formed on the arm 16, the lever being provided with a projecting finger 21 against which operates a spring 22 abutting a finger 23 onthe arm 16 whereby the lever 19 is maintained in contactfwith finger 20.

Brackets 2 1 are secured to the window frame, in approximately the position illustrated in Figure l of the drawings, and each bracket is bent back upon itself to form' a channel, the outer wall of the channel being formed with a recess 25 which is adapted for receiving a pin 26 which is secured to the lever 19. It is to be observed however, that when the mechanism is in the normal position that the arm 16 is in practically a straightvertical line which causes the finger 20 to engage the lever 19 to maintain the lever in a position where the pin 26 cannot engage in the recess 25.

The operation of the parts as described in moving the sash from the position illustrated in Figure 2 of the drawings to that illustrated in Figure 5 causes the lug 12 and the stud 18 to be moved correspondingly. The movement of the stud 18 which is engaged by the fingers 17v causes the arm 16 to be moved to the angular position illustrated in Figure 5, the spring 22 causing the lever 19-and the pin 26to also be moved. The .upper sash must be slightly lowered and'the lower sash must be slightly'raised to permit it to be swung thusly and continued movement vertically will cause the pin 26 to snap into the recess 25,

, the brackets being so located that they maintain the window at a venient for cleaning. In this manner the sash may be locked at a determined height by a mechanism which only locks it when the sash is swung out of the vertical position, the locking mechanism being releasable only by returning the sash to the closed position.

To lock the sash in the normal, vertical height which is conposition there is provided a locking mechanism which will not allow it to break inwardly on its pivot of its own accord or by air pressure, the mechanism comprising a spring 27 secured at its lower end by the screws or rivets 28 to the channel member 7. The channel member is provided with an opening 29 through which a dog 30, secured to the spring 2?, extends to engage in the opening 31 in the plate 3. T he upper end of the spring is provided with a finger piece 32 by which the spring 27'may be moved to withdraw the dog 30 from the opening 31 in order to unlock the sash so that it may be swung on its pivot to a horizontal position or to a ventilating position as will be subsequently described.

To partially open the sash in order to supply ventilation the plate 3 is provided with a slot 33 extending transversely of the window and having a slot 34 formed-connecting thereto and extending upwardly substantially midway of said slot 32 as is clearly in dicated in Figures 2 and 5 of the drawings. A pin 35is secured to the channel member 7 and is adapted to project into the slot 37 whereby a slight upward movement of the entire sash, a releasing of the previously described locking mechanism 27, and a slight movement inwardly at the upper end of the sash will cause slight downward movement of the sash whereby the slot 34: engages over the pin 35 and locks the sash in the position illustrated in Figure 6 of the drawings.

As a safety measure to prevent the sash from dropping, when the locking mechanism is released, so that the lug 12 could fall through the slot 8 there is provided a pivoted catch member 36. The catch member normally hangs by gravity so that the hook portion 37 projects across the slot 8 whereby to engage the lug 12 if the sash should drop as above described.

Although a specific embodiment of my invention has been illustrated and described it is to be understood that various alterations may be made in the details of construction without departing from the spirit of the invention as depicted in the appended claims.

What I claim is 1. A window construction comprising in combination a. frame, slotted side members slidable longitudinally in said frame, a sash member received between said side members, and means carried by said sash member and engaging in the slots in said side members whereby said sash may be swung pivotally to a horizontal position, latches carried by said side members and actuated by said first named means whereby the swinging of said sash member causes said latches to engage said frame whereby to prevent longitudinal movement of said side members while said sash is in, horizontal position. 1
